CARBURETING GAS-LAMP.

SPECIFICATION forming part of Letters Patent No. 381,934, dated May 1, 1888.

Application filed October 15, 18E?. Serial Xo. 252,495A '(No model.)

To all whom, it may concern:

Be it known that I, ARTHUR KITsoN, a subject of the Queen of Great Britain, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Carbureting Gas-Lamps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make anduse the same.

v The objects of myimprovernents are,first,to provide a simple device for regulating the proportion of enriched gas flowingto the burners; second, to provide a simple means for shutting oft' simultaneously thegas and hydrocarbon vapor from the burners; third, to provide a cheap valve for turning thegas on and owhich shall be unaffected by the heat from the gasflames; and, lastly, to provide means for turning the gas flames low without their liability to smoke.

Heretofore regulators which have been used for proportioning the amount of unenriched gas flowing to the burners have consisted of three-way stop cocks, buttertlyvalves, and similar contrivances, all of which are expensive, and very liable to clog and become useless.

It has been customary heretofore to turn the gas on" from the burners by a lever cock placed above the burners, which became stiff and difficult to manipulate, owing to the expansion by the heat from the Eames.

Heretofore the hydrocarbons in the carburetors have been at all times exposed to the atmosphere through the burner-arms and burners, the result being that after burning the lamp for several hours the hydrocarbons have been reduced to a highly-volatile condition, and an escape of the vapor has ensued, after shutting ott" the gas from the burners,into rooms and apartments where used, producing an exceedingly disagreeable and offensive odor.

.Myinvention electnally obviates these evils.

Heretofore it has been found impossible to turn the ames of carbureting gas-lamps low without producing smoke, the reason for which is that the supply of enriching vapor has remained constant, while the supply of gas has pipe, C the carburetor, and B Bthe gas burn-- ers.

A is a metal collar containing the burnerarms, and attached to the supply-pipe P. Thel upper central. hole of the collar A is screwthreaded, and engages similar screw-threads on the lower end'of the suppl y-pipe.

' O O are holes in the sides of the supplypipe, near its lower extremity, which may be made of any size, and are shown in drawings as closed by the metal collar A and asbestos Washer a. These holes may be opened by turning the collar around the pipe P, and the gas in pipe P conveyed directly to the burners. The amount of unenriched gas conveyed by these means direct to the burners can be prop'- erly adjusted by opening or closing the holes O O more or less. The asbestus washer a serves to keep the collar A and supply-pipe gas-tight and prevent leakage.

N is the neck of the sectional view of a carbureting vessel, screw threaded, and supported by the collar A, as shown.

L is a metal bushing, which serves to hold the asbestus Washer a in position and pressed close against the screw of neck N to prevent escape of gas.

R is a metal piece drilled through its een# ter and countersunk at its under side, as shown. It is firmly secured to the bottom of supplypipe. Directly under this piece is the corresponding metal plug, V, supported by the pieces m m, and springs S S-to the bottom of the neck of carburetor.

V is screw-threaded, and can be raised and lowered in its supports mm by screwing it up and down. The top of the plug is shaped to tit exactly the countersink in the piece R.

S S are metal springs, which secure the pieces m m to the bottom of N.

The object of the pieces V and R and their supports is to open and close the supply-pipe P, thus forming an equivalent for the ordinary stop-cock. This valve, as will be seen, is op- IOO erated by turning the carbureting vessel. By screwing it up the plug V closes the pipe P, and by unscrewing it the pipe is opened.

It will be noticed that the burner-arms are placed on sides of collar A, just below the asbestus washer a. The object of this is to enable the neck N to close off the gas and carbon v apor from the burners instantly by screwing the neck N against the asbestus washer a', which is done by means of the handle H. The top of N is made sharp, as represented, to make a perfect joint with the washer a.

Fig. 2 is.a plan ofthe piece V, with its supports m m and the neck N of carburetor.

The lamp is operated as follows: To light the burners, the handle H is turned once or twice in the direction of unscrewing. This opens the supply-pipe and passage-ways to the burners and admits gas to the burners, as shown by the arrows, which first descends into the carburetor, becoming enriched and rising to the burners. Should it be found necessary to reduce the degree of enrichment, the collar A, together with carburetor C, is screwed up on the supply-pipe by the burnerarms B B. This opens the holes O O, and a portion of gas unenriched escapes direct to the burners. The saine movement brings the plug V nearer to R and partially closes the supply of gas to the carburetor.

It will be seen that thesame movement which closes the supply-pipe P by turning H brings the neck N against the washer a. To enable N and plug V to operate exactly and simultaueously, the springs S S are employed. The plug V closes itsvalve slightly in advance of N, and the springs S S allow for the eXtra movement necessary to bring N in close contact with its seat a.

The closing of the supply-pipe and carbureting-vessel at one and the same time in the manner shown permits the flames to be burned at any height without smoking, as the proportion of enriching vapor is altered to correspond to the amount of gas consumed. It will therefore be seen that the regulation of unenriched gas supplied to burners is effected by the holes O O and collar A; that the hydro carbon vapors are shut off from the atmosphere at the same time the gas is turned off by means of handle H and parts P R and N a.

The latter are unaected by the heat and are simpler and cheaper to construct than ordinary stop-cocks, which theyreplace.

I wish it to be understood that I do not conne myself to the exact details herein speciiied; but

VVhatI claim, and desire to secure by Letters Patent, is-

1. In a carbureting gas-lamp, the combinal tion, with the carbureting-vcssel, ofa supplypipe having passage-ways in its sides, and a burner -support attached to said pipe and adapted to open and close said passage-Ways.

2. In a carbureting gas-lamp, the combination, with a carbureting-vessel, gas-burners, and burner-support, of a valve situated at or near the burner-support and adapted to open yand close simultaneously all of the burner passage-ways leading to the carbureting-ves sel and to the gas supply, substantially as de scribed.

3. In a carbureting gaslamp, the combination, with a carbureting-vessel, a gas-burner, and a burnersupport, of a gas-supply pipe terminating in the neck or mouth of the carbureting-vessel, and a valve placed at the termiuation of said pipe adapted to admit and f" shut off the gas,from said pipe to the gasburners and carbureting-vcssel, substantially as described.

4. In a carburetiug gas lamp, the combination of a gas-supply pipe, a gas-burner, aburner-support internally grooved and screwthreaded, and an asbestus washer placed at end of said groove, with a carbureting-vessel detachably connected to said burner-support by an elongated screw-threaded neck, which engages the similar screw-threads in said groove, and arranged to make a gas-tight joint with thepsaid washer, and a packed joint or stuing-box attached to the lower end of burner-support, substantially as and for the purpose herein described.

5. In a carbureting gas lamp, the combination, with a gas-burner and burnersupport, of a carbureting-vessel detachably connected to said burner-support by a neck, said neck forming, with its connection to the burnersupport, avalve adapted to open and close the passage-ways leading from the burners to the carbureting-vessel, substantially as described.
